This study characterizes tactile and temperature perception on the human torso through psychophysical tests, revealing site-specific differences in pleasantness, intensity, and sensitivity.

This study shows that the perceived intensity of vibrotactile stimuli is strongly influenced by vibration waveform, frequency, and amplitude, with square waves being perceived as more intense and perceived intensity peaking around 150 Hz.

The paper uses intraneural microstimulation combined with MEG to study cortical responses to touch afferents, finding consistent beta rhythm modulation in primary somatosensory cortex.
